Hello.
Our shielded 500 Oxford was de-energized in San Diego, moved across the
country and re-energized seamlessly by Dr Feng Qui of NMRqualytics. Everything
went very well, the old magnet is now in use, and with new o-rings the Helium
retention time is like new.
Best,
Anna De Angelis (Salk/UCSD)

In my experience, 60 MHz or 80 MHz benchtop instruments are extremely useful
for sparse, sensitive nuclei, like 31P or 19F, where the sensitivity penalty
can be tolerated and second-order coupling does not matter.
Observing a 13C spectrum can be lengthy, and interpretation of 1H can be
complex.

Hello NMR community,
Due to budget constrains, we are exploring the options of temporary shutdown
of our Bruker 300 or 600 MHz nmr. Could you please share the contact information
of vendors to get a price quote to De-energize Bruker 300 or 600 nmrs. What
will be the typical cost to Decommission and Recommission after few years
for these Magnets.
Is benchtop nmrs good enough for academic labs involving experiments with
multi-nuclei(1H, 2H, 13C and 31P) and what are the practical drawbacks
associated with benchtop nmrs. What is the cost for the benchtop nmr (80 MHz)
and any maintenance costs associated with the benchtop.
Thank you.
